Arc: Start Your Training

Your self-coached training, built around you. A plan that adapts every week to how you actually recover — whether you're chasing a race or just getting fitter.

Arc is your self-coached endurance training partner. Answer a few quick questions and Arc builds a personalized plan — then adapts it every week to how your body is actually recovering. No coaching degree required.

Whether you're training for your first race or just want to get fitter and build a consistent habit, Arc meets you where you are and explains every step in plain English.

BUILT AROUND YOU • Tell Arc your goal and schedule, and it generates a structured, periodized plan that ramps up sensibly and eases off before race day. • No race? Choose "Get fitter" for a rolling plan that steadily builds your fitness with recovery built in. • Beginner-friendly throughout: tap any training term to learn what it means, with gentle defaults so you never feel overwhelmed.

READINESS FROM APPLE HEALTH • Arc reads recovery signals like resting heart rate, heart rate variability (HRV), and sleep to estimate how ready you are to train hard today. • A simple 0–100 score with a plain-English call: push, hold steady, or take it easier. • Add a quick daily check-in to sharpen the picture on days with little data.

ADAPTS AS YOU GO • Each week Arc reviews your training and recovery and suggests adjustments — easier, harder, or unchanged. Nothing changes until you approve it. • Life happens. Arc keeps your plan realistic instead of guilt-tripping you.

TRAIN ACROSS YOUR DISCIPLINES • Running, cycling, swimming, and strength — with key sessions focused on your goal. • Clear daily workouts broken into easy-to-follow segments with intensity targets.

WORKS WHERE YOU DO • Apple Watch app and complications to see today's session and readiness at a glance. • Home and Lock Screen widgets. • Export your plan to Apple Calendar. • Import completed activities so your plan reflects what you actually did.

MAKE IT YOURS • Choose an accent theme and light or dark appearance. • Metric or imperial units.

PRIVACY FIRST • Arc reads recovery and workout data from Apple Health to personalize your plan. It never writes to Health, and your data stays on your device and in your private iCloud.

ARC PRO • Health-driven readiness, automatic weekly adaptation, and morning check-in reminders are part of Arc Pro. • Subscriptions are billed through your Apple Account and can be managed or canceled anytime in Settings.
